A CORPORATION OF NEW JERSEY WOOD-HEEL MACHINE Application filed June 27,1925.

he present invention relates more particularly to machines for shankshaping Louis heels. Some features of the invention are, however, ofmore general application.

The nature and the objects of the invention will be better understood inconnection with the accompanying drawings, in which Fig. 1 is aperspective view of a completed Louis heel; Fig. 2 is a side elevationof a machine constructed according to a preferred embodiment of thepresent invention; Fig. 3 is a plan of the same; Figs. 4 and 5 aresections taken upon the lines of Fig. 3 and 55 of Fig. 2, respectively,looking in the directions of the arrows; and F5 gs. 6 and 7 are,respectively, front and rear elevations of the same.

In the illustrated machine an alreadygrooved Louis heel blank (havingits breast surface already formed, but having its shank lip straight onits under side), is turned past a shank shaping tool in a circular pathabout an axis lying beyond the attaching face of the blank, with theshank lip lying between the axis and the tool. This operation rounds thelower surface of the lip. The curvature of the lip surface formed isdetermined by the distances of the axis from the lip and tool, and thesedistances are adjustable, as will be seen.

A previously grooved wood-heel blank 2 is adapted to be clamped betweenlower and u )per 4 and 6 of a clamp 8. The heel blank is at this timeprovided with a projecting lip or shoulder 7, included between parallel,straight lines 9 and 11. A shaping tool 14, that is rotatable upon ahorizontally disposed shaft 16, mounted on the machine frame 40, extendsover a centrally disposed portion of the lip 7, and into the bottomportion of the breast groove 18 of the clamped blank when the latteroccupies its normal, illustrated position. The clamp is actuated about ahorizontally disposed pivot 10, to the I right and to the left of thesaid normal position, as viewed in Figs. 6 and 7, as indicated by thearrows. This may be done by means of a handle (not shown) or by merelygrasping a portion of the clamp 8, as the arm por tion 86. The shoulder7 becomes thus circu- Serial No. 39,954.

larly shaped by the cutter 14, on each side of the said centrallydisposed portion, along the curved lines 20. 22. The blank is thenremoved from the clamp and another blank substituted. In order that thecurves 20, 22 may be symmetrically disposed, it is necessary to have theblank 2 centered between the jaws 4 and 6, and this may be effected byusing guiding fingers 24, 26., These guiding fingers automaticallycenter the blank in proper position under the influence of a spring 12which forces the fingers forward against the heel blank 2. The fingersand the clamp arm 86 are shown carried upon a common slide 13, betweenguides 15, so that the blank may be clamped and centered simultaneously.Theposition of the blank towards and from the cutter 14 is adjusted bymeans of an adjustable gage 28 that is engaged by the shoulder 7. Theangular position of the blank may be adjusted to conform to the groove18 in the heel by pivotally elevating the jaw 4 about a horizontallydisposed pivot 30 that is perpendicular to, and positioned above, thepivot 10.

Provision is made for adjusting the pivot 10 vertically, or at rightangles, to the lip 7, in order that its distance from the cutter 14,underneath which it is disposed, may be varied, in order to vary theradius of curvature of the lip surface formed. Such adjustment makes itpossible to conform to the concave 18 in the heeland to gage thethickness of the shoulder or lip 7 This adjustment may be effected inany desired way. It is preferred to mount the pivot 10 in a bearing 32provided at the upper end of a plate 34 that is vertically slidablebetween vertically disposed guides 36. The guides 36 are preferablyintegral with a bracket 38 that is horizontally adjustably secured tothe frame 40 of the machine in any desired way, as by means of apin-and-slot connection 42, 44. The position of the bracket may thus beadjusted to and from the tool 14. The plate 34 may be verticallyadjusted by means of a threaded member 46 that is threaded into theplate at 48 and that is held against vertical movement by a cross bar 50on the bracket 38. The cross bar 50 is secured to the bracket 38 byscrews or the like 52 and is provided with an opening 54 through whichthe member 46 extends and with respect to which it is rotatable. Collars56 provided upon the threaded member -16, and between which the bar isconfined, hold the member 46 against vertical movement. After the plate84 has been vertically adjusted to the desired degree, it is clamped inadjusted position by a clamp screw or bolt 58 that extends through avertically disposed opening 60 in the plate 34? and that may be threadedinto the bracket 38.

In addition to adjusting the distance of the pivot 10 from the cutter14, it is desirable to shorten and lengthen correspondingly the radiusof the are described by the blank about this pivot and, therefore, theradius of curvature of the curves 20, 22. To this end, the jaw 4 ispivoted at 30 to a plate 62 that is adjustable towards and from thepivot 10. This latter adjustment is effected by means of grooves 64,vertically disposed in the plate 62, within which are mounted tongues 66provided upon a plate 68, which is pivoted to the plate 34 at 10. Afterthe plate 62 has been moved farther from, or nearer to the pivot 10, bymeans of this tongue-and-groove arrangement, it is clamped to the plate68 by a clamp bolt and nut 70 extending through vertically disposedopenings 12 in the plate 62 and the plate 68.

The plate 62 is provided with a projection 74 in which is verticallythreaded an adjusting screw 76, the free end of which engages the aw l.It is by means of this adjusting screw that the jaw a may be pivotallyelevated about the pivot 30. The under portion of the l is provided withlugs 31, each having a horizontally disposed opening within which areslidably mounted rods 78. The gage 28 is carried at the ends of theserods. By sliding the rods '58 back and forth, therefore, the position ofthe gage 28 may be adjusted. Therods 78 may be clamped in adjustedposition by nuts 84 or in any other desired manner.

In addition to the above-described adjustients, it is necessary also tomake provision for the clamping of heel blanks of different sizes. Thisresult may be attained by making one of the jaws adjustable. It ispreferred to have the jaw 6 constituted of a clamping screw that is adjustably mounted in the arm 86 of the clamp. The position of the screwupon the arm 86 determines the size of the blank that will be clamped.

In operating the machine the operator draws back the slide 13 againstthe spring 12, inserts the heel blank between the fingers 24, 26, andthen allows the spring 12 to force the blank forward against the stop28, with its lip under the tool 14. He then swings the blank from sideto side to enable the tool to round off the lip, as shown in Fi 1. The

thickness of the lip is controlled by the adjustment at 70, and thecurvature of the lip by combined adjustments at 70, 58. In effect, inchanging the curvature of the lip, the blank 2 and tool ll are kepttogether and the pivot 10 is raised or lowered on the slides at 64 and36. Y

It will be understood that the invention may be modified by personsskilled in the art vithout departing from its spirit and scope, asdefined in the appended claims.
